The shuttlecarrier 26 is provided adjacent its periphery with theV forwardlydirected arm or lip 29 arcuate in cross section and which is adapted tobe received vwithin the recess Y30 formed in the Vperiphery of theshuttle S whereby it will beperceived that the shuttle S will be causedto'rotate inunison-with and in the same general direction as the carrier26. j Y

v The shuttle S is adapted to have rotatably supported therein thebobbin B and the vthread from Vthe bobbin is directedthrough Yico withthe nose 32 adapted to engage theV thread brought within Ythe chamber 27by theneedle N whereby the requisite stitch is formed. It is also'to beobserved that the needle N passes over ythe forward face of the shuttleS. V v f r In order to facilitate the insertion or removal of theshuttle S the VVouterjend of the chamber 27 is Vnormally open but isVadapted tobe closed by the plate 33 having its inner face'provided withthe inwardly directed flange 34- disposed-on an annular line to assurethe requisite clearance forV the movement of the needle within thechamber 27 and which also contacts with theouter face of the shuttle StoV cause the same totravel in a fixed path. Y 1 g VThe plate 33 isprovided adjacent its upper end with a laterally and outwardly directedwing 35 providedwith a perforation 36through which is directed'theforwardly extending threaded shank 37 carried by the block 28. yTheinnerportionof the perforation 36V is enlarged toY accommodate the Ywasher 38threaded upon the shank 37 and providedY with the notch 3.9 adapted toreceive the pin 40 carried bythe wing 35 vand whereby said washer 38servesinfthe nature of a'jam-nut. The outer end portion of the threadedshank 37 has engaged therewith the clamping nut 41 for a purpose whichis believed to be self-evident.

The shank 37 has its inner end portion smooth and loosely disposedwithin the recess or pocket 42 formed in the block 28 and has its innerend provided with a head 43. interposed between the head 43 and theouter endfof the pocket 42 is the eX- pansible member 44 hereindisclosed as a conventional coilV spring encircled around the shank 37whereby it will be perceived that the plate 33 is capable of slightyield-Y able movement relative to the block 28 in order Ithat the stitchoperation may be materially facilitated.

The periphery of the plate 33 at the side opposite to the wing isprovided with a recess or pocket 45 Vwhich is adapted to receive thespring-pressed locking member' 46 slidably disposed through 'theadjacent portion of the block 28 or more particularly the face plate 47secured thereto. The plate 47 is of such a length as to substantiallyentirely bridge the space between the lower portion of theblock 28 andthe upper face of the table 7 It is also to be noted that the upperportion of the block 28 is provided with an opening 48, the forwardwalls whereof being ared in order to eliminate any obstruction to themovements of the threads during the stitch forming operation. f

The forward portion of the block 28 is provided with the upstandingportion 49 aifording a straight horizontal surface serving as a worksupport, and said portion l49 is provided with the recess 50 for thepassage of the needle N.

Coacting with the portion 49 is the presser foot 51 suitably secured tothe lower ends of the parallel arms 52 depending from the' slide 53mounted for reciprocating movement within the guideway 54 formed in theforward face of the plate 16 adjacent the upper end thereof, saidpresser foot 51 bridging the space between the lower ends of the arms 52and provided therebetween with the opening 55 alining with the recess 50and through which the needle N is also adapted to pass. The slide 53 isprovided with a laterally directed web or wing 56 from which `extends aninwardly directed b in 57.

Secured to said pin 57 isan end portion of the retractile member 58, theopposite end portion of which being secured to the plate 16at apredetermined point below said web or wing 56` said retractile member 58being herein disclosed'as a conventional coil spring and serving toautomatically impart downward movement to the slide 53 in order to causethe presser foot 51 to properly engage the work.

The web or wing 56 has also operatively engaged therewith a link 59which is also pivotally engaged to the arm 60, said arm 60 beingsupported for rocking movement by the plate 16 and the connection 61between the arms 60 and link 59 being eccentric tothe connection 62between the arm 60 and the plate 16, whereby 'it will be perceived thatupward movement of the arm will result in the elevation of the slide 53.

63 denotes a pawl pivotally supported by the arm 64 extending laterallyfrom the plate 16 and which engages'the upper portion of the web or wing56 to hold the slide 53 against undue upward movement when the same hasbeen adjusted to bring lthe presser foot 51 in operative engagement withthe work. As herein embodied, the upper portion of the pawl 63 hascoacting therewith the eXpansible spring 65 for forcing the lower end ofsaid pawl inwardly. It is also to be noted that the lower end of thepawl 63 is toothed, as at 66, to facilitate its coaction with the wingor web 56 and it is also to be noted that the lower end portion of saidpawl 63 is provided with the shoulder 67 with which the upper end of thelink 59 is adapted to contact in order to disengage 'the pawl 63 fromsaid wing or web 56 upon the initial upward movement being imparted tothe arm 60 to raise or elevate the slide 53.

The inner or rear face of the slide 53 is provided with the guideway 68in which is arranged the needle bar 69. said needle bar 69 and slide 53being arranged forrelative independent reciprocal movement.

As is particularly illustrated in Figs. 9 and 10, the lower end portionof the needle bar 69 is provided with a slit 76 in communication withthe bore thereof so that the needle N may be effectively held by theneedle bar through the medium of the clamping screw 71.

The needle bar 69 at substantially mid,- way its length is provided withthe rearwardly directed pin 72 loosely disposed through the upper endportion of the operating member 18 whereby it will be perceived thatupon reciprocation of the member 18 under the influence of the footlever 12, the requisite movement will be imparted to the bar 69. Itisalso to be noted in Fig. 8 that the teeth 23 of the operating Lmember 18are interrupted adjacent the lower part thereof so that the shuttlecarrier 26 will remain stationary during a portion of the movement ofthe operating member 18 and during a portion of the movement of theneedle N. so that the needle N will have suflicient time to form theloop to be engaged with the under thread.

The pin 72 extends beyond the rear face of the operating member 18 andis loosely disposed through the elongated slot 73 produced in the lowerend of the rod 74 which extends upwardly 'and through the top' plate andhas its upper extremity operatively engaged, as at 76, with the take-uparm 77.V

Y p Y The second bar 22 adjacent its lower end is provided withthe inwardly Ydisposed teeth 104 which are adaptedto engagethe teeth ofthe disk 105 carried by the shaft 106 disposedthrough the plate 16,whereby'it will be perceived that the shaft 106 will be intermittentlyrotated'in opposite directions.

rlhe forward end of the shaft 106 has affixed thereto a head 107 towhich is Vpivotally engaged the lateral extension 108 of the feed arm109, and said feed arm 109 is adapted to bemoved about its pivotindependently of the rocking movement ofthe head 107 through the Vmediumof the retractile memberrllO Vsecured'at one end tothe lower portion ofthefeed arm 109 and to the depending portionV of a side plate 111secured to the block 28,'said platelll having threaded therethroughthermemberl112 which vserves to limit the extent of rocking movement ofthe feed arm 109 under the influence of the retraotile member 110,whereby the extent of feed of the work may be regulated. v Y

The rupper end p'ortion'offthe feed arm 109 is disposedinwardly, as at'113, toward the portion 49 and is provided with the upstanding pointsor awls 114 to impinge the under surface of the work in order to forcethe same in the requisite' direction. It will be'perceived that when thefoot lever 12 is depressed, Vthe feed arm ,109 vwill be lowered'predetermined'extent.V p Upon the initial-.roytation of the head Y107thearm .109V will be caused to move upwardly. The head 107-is adaptedto-contact with the'lateral extension 108 ofthe arm 109'to cause theupper portion of said arm109 to rock in a direcltion toward-the portionVor work support 49 Y' upon the continued 'iipwa'rd rotation'of'the 1head 107.@ iso .l

In order that the thread may be properly waxed and particularly theunder thread, we employ the wax containing box or cup 116 pivotallyengaged with the under surface of the table 7 adjacent an end thereof.The box or cup 116 is preferably rectangular in form and is adapted tocontain a suitable quantity of thread wax. In the opposite end walls ofthe box or cup 116 the rod 117 is loosely mounted to rotate. Theintermediate portion of this rod 117 is upwardly offset, as at 118, toaord a guide for the thread as it passes through the box. The rod 117 isalso provided upon one of its ends and exteriorly'of the box 116 with anoperating member 119. The opposite side walls of the box 116 areprovided at a central point and adjacent their upper edges with theopenings 120 through which the thread is adapted to extend.

Upon the outer face of one of the side walls of the box or cup 116 andadjacent to the opening 120 therein, is secured the plate 121 whichserves as a support for a piece 122 of leather or other suitablematerial and which is maintained in applied position through the mediumof the screw 123. The thread as withdrawnk from the box or cup 116passes beneath this piece of leather or the like and the tension orpressure of said piece 122 upon the thread may be regulated as requiredby the screw 123. 1t will be apparent that in this manner the surpluswax upon the thread may be removed as the thread is drawn from the waxbox or cup 115.

12-1 denotes a tank secured to the under surface of the top plate 75 andadapted to contain a Source of fuel supply and leading from said tank124 is the pipe 125 in communication with the burner 126 rotatablysupported below the table 7. It will lbe perceived that the burner 126may be conveniently adjusted below the box or cup 116 inv order to meltthe wax therein or to maintain the same in a molten condition.

The burner 126 may also be swung beneath the :[iue 127 depending fromthe table 7 and discharging therethrough below the block'28 whereby thethread wound upon the bobbin B within the shuttle S may be maintained atsuch a temperature to prevent undue hardening of the wax thereon. Y

Frein the foregoing description, it is thought to be obvious that asewing machine constructed in accordance with our invention is of anextremely simple and comparatively inexpensive nature and isparticularly well adapted for use by reason of the convenience andfacility with which it may be assembled, and it will also be obviousthat our invention is susceptible of some change and modificationwithout material departurefrom the principles and spirit thereof and forthis reason we do not wish to be understood as limiting ourselves to theprecise arrangement and formation of the several parts herein shown incarrying out our invention in practice, except as hereinafter claimed.
